Flat Rate Interest Formula:
| From: | To: |
Flat rate interest is a simple method of calculating interest where the interest is calculated on the original principal amount throughout the entire loan tenure, without considering any repayments made. It is commonly used in real estate and personal loans.
The calculator uses the flat rate interest formula:
Where:
Explanation: The formula calculates the total interest payable over the loan period based on the original principal amount.
Details: Understanding flat rate interest helps borrowers compare different loan options and understand the total cost of borrowing. It provides a straightforward way to calculate interest payments for real estate transactions.
Tips: Enter the principal amount in dollars, annual interest rate as a decimal (e.g., 0.05 for 5%), and tenure in years. All values must be positive numbers.
Q1: What's the difference between flat rate and reducing balance interest?
A: Flat rate calculates interest on the original principal throughout the loan term, while reducing balance calculates interest on the outstanding balance, which decreases over time.
Q2: Is flat rate interest better for borrowers?
A: Generally, reducing balance interest is more favorable for borrowers as it results in lower total interest payments compared to flat rate interest for the same nominal rate.
Q3: How do I convert percentage rate to decimal?
A: Divide the percentage by 100. For example, 5% becomes 0.05 as a decimal.
Q4: Can this calculator handle monthly calculations?
A: This calculator uses annual calculations. For monthly calculations, convert the tenure to years (divide months by 12) and use annual rate.
Q5: Are there any limitations to flat rate interest calculation?
A: Flat rate interest doesn't account for the time value of money and may overstate the true cost of borrowing compared to more sophisticated methods.
